VietTTS: An Open-Source Vietnamese Text to Speech

VietTTS is an open-source toolkit providing the community with a powerful Vietnamese TTS model, capable of natural voice synthesis and robust voice cloning. Designed for effective experimentation, VietTTS supports research and application in Vietnamese voice technologies.

⭐ Key Features

TTS: Text-to-Speech generation with any voice via prompt audio
OpenAI-API-compatible: Compatible with OpenAI's Text-to-Speech API format

🛠️ Installation

VietTTS can be installed via a Python installer (Linux only, with Windows and macOS support coming soon) or Docker.

Python Installer (Python>=3.10)

bash

git clone https://github.com/dangvansam/viet-tts.git
cd viet-tts

# (Optional) Install Python environment with conda, you could also use virtualenv 
conda create --name viettts python=3.10
conda activate viettts

# Install
pip install -e . && pip cache purge

Docker

Install Docker, NVIDIA Driver, NVIDIA Container Toolkit, and CUDA.
Run the following commands:

bash

git clone https://github.com/dangvansam/viet-tts.git
cd viet-tts

# Build docker images
docker compose build

# Run with docker-compose - will create server at: http://localhost:8298
docker compose up -d

# Or run with docker run - will create server at: http://localhost:8298
docker run -itd --gpu=alls -p 8298:8298 -v ./pretrained-models:/app/pretrained-models -n viet-tts-service viet-tts:latest viettts server --host 0.0.0.0 --port 8298

Command Line Interface (CLI)

The VietTTS Command Line Interface (CLI) allows you to quickly generate speech directly from the terminal. Here's how to use it:

bash

# Usage
viettts --help

# Start API Server
viettts server --host 0.0.0.0 --port 8298

# List all built-in voices
viettts show-voices

# Synthesize speech from text with built-in voices
viettts synthesis --text "Xin chào" --voice 0 --output test.wav

# Clone voice from a local audio file
viettts synthesis --text "Xin chào" --voice Download/voice.wav --output cloned.wav

API Client

Python (OpenAI Client)

You need to set environment variables for the OpenAI Client:

bash

# Set base_url and API key as environment variables
export OPENAI_BASE_URL=http://localhost:8298
export OPENAI_API_KEY=viet-tts # not use in current version

To create speech from input text:

python

from pathlib import Path
from openai import OpenAI

client = OpenAI()

output_file_path = Path(__file__).parent / "speech.wav"

with client.audio.speech.with_streaming_response.create(
  model='tts-1',
  voice='cdteam',
  input='Xin chào Việt Nam.',
  speed=1.0,
  response_format='wav'
) as response:
  response.stream_to_file('a.wav')

CURL

bash

# Get all built-in voices
curl --location http://0.0.0.0:8298/v1/voices

# OpenAI format (bult-in voices)
curl http://localhost:8298/v1/audio/speech \
  -H "Authorization: Bearer viet-tts" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "tts-1",
    "input": "Xin chào Việt Nam.",
    "voice": "son-tung-mtp"
  }' \
  --output speech.wav

# API with voice from local file
curl --location http://0.0.0.0:8298/v1/tts \
  --form 'text="xin chào"' \
  --form 'audio_file=@"/home/viettts/Downloads/voice.mp4"' \
  --output speech.wav

Node

import fs from "fs";
import path from "path";
import OpenAI from "openai";

const openai = new OpenAI();

const speechFile = path.resolve("./speech.wav");

async function main() {
  const mp3 = await openai.audio.speech.create({
    model: "tts-1",
    voice: "1",
    input: "Xin chào Việt Nam.",
  });
  console.log(speechFile);
  const buffer = Buffer.from(await mp3.arrayBuffer());
  await fs.promises.writeFile(speechFile, buffer);
}
main();
